The existing land drainage system comprises of surface drains with thick weed growth and unstable due to coasted soil predominantly silty sand with non cohesive texture. The water table is high which has caused water logging. To improve the system, underground drainage network connected to the pumping stations and final disposal to the sea has been proposed.
